In the last 05 months, 86.75% of health care workers were subjected tornviolence; and furthermore, 86.6% were subjected to psychological violence andrn19.9% to physical violence. For physical violence, being married and more yearrnof experience were found to be victimized by 1.66 times and 5.18 times less likelyrnthan living with a partner and a less year of experience. However, forrnpsychological violence, being single was 3.070 times less chance of beingrnattacked psychologically than being married. Overall, relatives were the mostrncommon perpetrators. Only 13.9% of the physically attacked and 5.1% of thernpsychologically attacked have reported their assault; and in only 22.2% of thernphysical assault and 10.9% of the psychological assault were formal investigationrndone.
